Quantum pumping in deformable quantum dots [PDF]

open access: yesPhysical Review B, 2009
The charge current pumped adiabatically through a deformable quantum dot is studied within the Green's function approach. Differently from the non-deformable case, the current shows an undefined parity with respect to the pumping phase . The unconventional current-phase relation, analyzed in the weak pumping regime, is due to a dynamical phase shift
